Allophylus dimorphus Radlk., a member of the Sapindaceae family, is a shrub or tree primarily found in the Nicobar Islands, Malaysia, and the Philippines. Despite its potential relevance in traditional medicine, research on the ethnopharmacological and medicinal properties of this species is currently limited. However, a few closely related species, such as Allophylus cobbe and Allophylus serratus, have been studied for their bioactive compounds with antioxidant, antimicrobial, and anti-inflammatory properties. The World Health Organization (WHO) recognizes the significance of traditional medicine, which remains a vital healthcare source for many communities worldwide. The rapid loss of plant diversity and the potential for discovering novel medicinal compounds highlight the necessity of documenting and investigating A. dimorphus and related species. This update consolidates existing knowledge on the phytochemistry, ethnomedicinal uses, and pharmacological properties of A. dimorphus, providing a foundation for future research and conservation efforts.
